Abstract Plain Text:

The production of muons from heavy-flavour decays has been studied with the ALICE experiment at the CERN LHC. The measurements have been performed at forward and backward rapidity corresponding to the center of mass rapidity regions 2.04 < ycms < 3.54 and -4.46 < ycms < -2.96, respectively. The production cross sections and nuclear modification factors are presented as a function of transverse momentum. While no suppression is evidenced with respect to binary-scaled pp collisions at forward rapidity within uncertainties, a slight enhancement is observed in the intermediate transverse momentum region 2 < pT < 4 GeV/c. The ratio of the forward to backward production cross sections is also measured. The data are described by perturbative QCD calculations including initial-state effects. The results confirm that the strong suppression that was measured in central Pb--Pb collisions at high pT is a final-state effect  related to in-medium parton energy loss.
